Exploring personality correlates of psychiatric hospitalization: A cross-sectional comparison of section ii personality disorder model and alternative model for personality disorders.

What is it about?

Our study demonstrates the utility of Section II of the DSM-5 diagnoses, as well as Criteria A and B of the AMPD, in predicting severe clinical outcomes like psychiatric hospitalization (PH). While each diagnostic method individually shows high discriminative performance, using all three concurrently for PH is not practical. Notably, there are interactions between these systems; the incremental value of Criterion A decreases when combined with Section II and Criterion B, particularly due to negative affectivity.

Why is it important?

The results of this study have implications for clinical practice, particularly in the area of PD diagnosis, and thus for risk assessment and treatment planning. As we are in a time of transition between traditional and new dimensional diagnostic models—especially after the ICD-11 was introduced—the clinician might literally face a dilemma concerning which diagnostic measure to use when considering a certain outcome. Our study provides some reassuring insight into this dilemma with both Section II and Section III of PD diagnoses demonstrating high accuracy in distinguishing between group with mental health crises manifested in PH and group without necessity of hospitalization. Even if a clinician’s resources are limited to a SCID-5-PD interview, it is still a robust tool to distinguish individuals experiencing a mental health crisis requiring PH from those whose mental state does not currently necessitate immediate intervention. Our data also suggest that the simultaneous use of all three measures may not be beneficial, as it can lead to redundant results.
